SPECIFICATIGN forming part of Letters Patent No. 498,625, dated may 2, 1893.

Application filed May 12, 1892. Serial No. 432,7 (N -l To all whom it may concerns Be it known that 1, WILLIAM H. TUTTLE, a citizen of the United States, residing at De- .troit, county of Wayne, State of- Michigan,

have invented a certain new and useful Improvement in Nails; and I declare the follow- I part of this specification.

a beveled cross-cut.

would lie at an angle.

This invention relates to nails, and has for its object an improvement in that class of nails which are especially designed to secure and hold together miter-joints or joints formed by placing two pieces of wood together, end to end, either with a straight cross-cut or with With-a straight crosscut, the two pieces of wood thus joined would lie in the same straight line; with a beveledcross-cut the two pieces of wood thus joined The nail may also be used in joining two pieces, which are squared oh, and of which one is' abutted against the other.

In the drawings: Figure 1, shows the nail in perspective. Fig. 2, shows two strips of wood cut to be united with a miter-joint and shows the nailpartially driven into its holding position. F! g. 3, indicates the position occupied by the nail when used to unite two pieces of wood, where the end of one is abut- -ted against the side of the other.

A, represents the nail made of sheet metal, having a body part or web a, and two upturned flanges b, c; at the point D, of the nail,'-the web or body-part is wider than it is at the head .2, and the flanges b, c, taper. gradually from the head to a short distance above the point at F, F and from F, to the extreme point taper down and disappear, so that the web part of, the nail is narrower at the head of the nail than at its point, and the two flanges are wider at the head than theyare at the point, and narrow slowly from the head to the points F, and then narrow rapidly to the extreme points G. This nail may be driven without any previous preparation in soft wood, but in hard wood it is usually desirable to cut with the saw a" gain or kerf, in the ends of the pieces to be joined, the depth of out being about equal in each piece to one-half the width of the wide or point end of the nail, and if the material be very thin,

drill or otherosimilar implement, a passageslight strain caused when the nail is forced The two pieces to be united into its position. are placed in the position they are to'occupy with respect to one another,and the nail is.

driven into the out if one has been'made, or into the wood if no out has been made. .The

peculiar shape of the nail, narrowing from the point to the vhead, causes it. to draw the parts tightly together and obviates the necessity of using great care to place the pieces P, P, with their outer sides exactly meeting. at the point p, as the nail will when driven 1n force the parts P, P, to meet along .the miterline P, P, along which line they may be adjusted after the joint.

What I claim as my invention is- 1. A nail for miter joints, consisting of side nail has been driven into the flanges, and a uniting web, the said uniting web, widening from head to point, and each of the said side flanges tapering from head to point and each beingturned up sharplyat an angle with the uniting web, whereby they are adapted to out into the wood tobe united, and draw the parts together as the nail is driven, substantially as and for the purpose specified. I

- 2. A nail for miter joints, consisting of two sideflanges, and a uniting web, the said side flanges tapering slowly from headto near the point, and then rapidly to the point, the said uniting 'wcb, widening slowly from head to point, substantially as and for the purpose specified.

In testimony whereof I sign this spe'cifica: tion in the presence oftwo witnesses. WILLIAM H. TUTTLE;
